Chile's football federation says it has been fined by FIFA for ticketless fans breaking through security barriers at Maracana Stadium, according to Reuters.
The Chilean federation did not specify the size of the sanction in a statement on its website, Reuters reported. FIFA has not yet announced the ruling from its disciplinary committee.
The ANFP did not give details of the fine but said it would be sanctioned far more harshly if Chilean fans are involved in any other incidents, according to Reuters.
"Yesterday (Monday) we got notice from FIFA's disciplinary commission that the Federation was being sanctioned with a fine for the incidents carried out by" Chilean fans who pushed down a perimeter fence outside the Maracana and allowed about 200 supporters to rush into the media center," the ANFP said in a statement, Reuters reported.
More than 80 Chile fans were detained by stadium staff in the security breach before their team's 2-0 win against Spain last Wednesday, according to Reuters.
The fans stormed the Maracana media center and broke down partition walls seeking a way to the pitch, Reuters reported. Brazilian authorities ordered the fans to leave the country within 72 hours or face arrest.
The Chilean federation says FIFA declined to impose sanctions for fans lighting fireworks in the Cuiaba stadium during its 3-1 win against Australia on June 13, according to Reuters.
Another investigation is ongoing after fireworks were set off during Chile's 3-1 victory over Australia in their opening Group B game, Reuters reported.
"If a third case is opened by the FIFA for new incidents in upcoming games, the sentence could be very hard and harsh for (our) economic and sporting interests," the Chilean federation said, according to Reuters. Chile have reached the World Cup last 16 and play hosts Brazil on Saturday in Belo Horizonte.
